R134A conversion...what all parts do you need?

[Teahead]

Need a new accumulator, right? E.g.:

Advance Auto Parts - Down for Maintenance

Doesn't show whether it's for both R12 or R134a.

Do we need a new R134a Switch?

Does the new accumulator need thread adapters for the above switch? ALso for the new low (on the accumulator) and high (on the pipe) tap ports?
Found this pic on the internet that looks like maybe it has adapters for R134a???

Of course, change the orifice tube.

You need to drain the oil out of the system and replace it, including draining the compressor. You should also flush the system out. Why are you changing to 134, since it is also being phased out? Why not just put in a drop in replacement, like Freeze12, where you can just put it in, with no changes?

Freeze 12 is R134a.

R134a is being phased out when? Like in 2050?

Freeze 12 is not 134, since it still uses mineral oil, which 134 can't do. They've already phased out 134 in a lot of vehicles already. By the way, after January 1,2024, you can no longer build new devices, that use 134

Rather than converting my system, I tried envirosafe artic air r-12 replacement frion. It works well for my truck.

Thanks. Having a guy give me options this week. 33K miles, original R-12, original everything. Just not enough pressure on the dryer to kick it on. I'll post results too so we all have an idea of whats available these days.
